Adjust rtx_cost for DF/SFmode AND/IOR/XOR/ANDN operations.
They should have same cost as vector mode since both generate
pand/pandn/pxor/por instruction.
gcc/ChangeLog:
* config/i386/i386.cc (ix86_rtx_costs): Adjust rtx_cost for
DF/SFmode AND/IOR/XOR/ANDN operations.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr110170-2.c: New test.
